With the offseason just around the corner, we wanted to give a refresher on contract incentives and their various forms. Signing bonuses can sweeten the pot for free agents and are largely self-explanatory, but incentives are a bit trickier.

At the most basic level, contract incentives are designed to reward a player for his performance — in some cases, these financial rewards are linked to individual or team production, while other incentives can be earned simply by the player earning a spot on his team’s active roster from week to week. These incentives are divided into two categories: Likely to be earned (LTBE) and not likely to be earned (NLTBE).

Under the NFL’s definition, a likely to be earned incentive is generally one that was achieved the year before. So if a running back racked up 1,300 yards on the ground in 2017 and has an incentive in his contract that would reward him for surpassing 1,200 yards in 2018, that incentive is viewed as likely to be earned and counts against his cap hit from the start of the year. On the other hand, a back who has never surpassed 700 rushing yards in a season could have an incentive on his deal for 2014 that would reward him for rushing for 800 yards — such a bonus would be considered not likely to be earned, and wouldn’t count against the player’s cap number.

Because the player’s or team’s performance in a given season dictates whether or not the incentive is actually earned, the player’s cap number is sometimes altered after the fact. For instance, there’d be no change if a player met the criteria for a $50K LTBE incentive, but if he failed to earn that incentive, his team would be credited with $50K in cap room for the following season. Similarly, if a $50K NLTBE incentive isn’t reached, nothing changes, but if a player does earn that incentive, his club’s cap space for the following season is reduced by $50K.

A simple incentive linked to yardage or touchdown totals in a season isn’t too hard to track, but there are more convoluted forms of bonuses. Let’s say a player coming off an injury that limited him to six games played signs a contract that would pay him $500K in per-game roster bonuses. That player would be considered likely to appear in six games, but unlikely to appear in more beyond that. So, of his $500K in roster bonuses, $187,500 would initially count against the cap, as the LTBE portion.

Here are a few more notes on contract incentives and how they work:

Any incentive that is considered to be in the player’s sole control, such as weight bonuses, or his presence at workouts, is considered likely to be earned.

Any incentive in the first year of a rookie contract is considered likely to be earned.

Individual performance incentives can be linked to most basic statistical categories, such as yardage, yards per attempt, and touchdowns. However, more obscure stat categories typically aren’t allowed for individual incentives. For instance, a receiver couldn’t have an incentive tied to receptions of 20+ yards. Meanwhile, a defender could have an incentive linked to sacks or interceptions, but not to tackles for a loss.

In some cases, individual performances can also dictate the value of traded draft picks. For example, the Jaguars making the playoffs this year altered their trade for Marcell Dareus. The Bills received a conditional 2018 sixth-round pick for Dareus in the parties’ October trade, but that pick became a fifth-rounder when the Jags reached the postseason.
